IMPROVED HINGE.

Specification forming part of Letters Patent No. 51,711, dated December26, 1865.

To all whom 'it may concern: n

Beit known that I, SAMUEL O. FEINK, of the city of Indianapolis, countyot' Marion, and State of Indiana, have invented a new and useful Hingefor Gates, VVindow-Shutters, Ste.; and I do hereby declare the followingto be a full and exact description thereof, reference being had to theaccompanying drawings, and to the letters and gures of reference markedthereon.

llhe nature of the invention consists in peculiar construction andoperation of said hinge. Said hinge to be made of brass or iron, or anyother metal suitable for that purpose.

To enable others skilled in the art to make and use 1nyinvention,Iproceed to describe it more particularly, as follows The hinge-plate Fof No. 2 of the said drawings is provided with a proper spindle, C, ofsaid N o. 2. On the said spindle O is cast a lug (represented by D ofsaid No. 2.) Over the said spindle C is placed the socket, (representedby A B G of Fig. 3 of said drawings,) the whole being, when in properposition, as represented by Fig. l of said drawings. The said socket A BGr is provided with a spiral slot, (represented by E of Fig.3aforesaid,)througl1 which the said lug D passes into the slot A G ofNo.1, aforesaid, where it is free to turn through half of a circle. Whenthe hinge is open, the said lug D, by striking against A. the bottom ofthe said slot A G, Will prevent thesaid socket A B G from being thrownoff ofthe said spindle O. When the hingeis shut, the said spiral slotorgroove having conveyed the said lug D below the said band B, the twoleaves ofthe hinge will be free to part.

What I claim, and desire to secure by Letters Patent, is-

p The combination of the said lug D, the spiral groove E, and the slot AG, when the same are constructed and operated substantia-lly as setforth.
